Background: Urinary tract infection (UTI) represents one of the most common infectious diseases and a major cause of antibiotic prescription in children. To prevent recurrent infections and long-term complications, low-dose continuous antibiotic prophylaxis (CAP) has been used. However, the efficacy of CAP is controversial. The aim of this document was to develop updated guidelines on the efficacy and safety of CAP to prevent pediatric UTIs. Methods: A panel of experts on pediatric infectious diseases, pediatric nephrology, pediatric urology, and primary care was asked clinical questions concerning the role of CAP in preventing UTIs in children. Overall, 15 clinical questions were addressed, and the search strategy included accessing electronic databases and a manual search of gray literature published in the last 25 years. After data extraction and narrative synthesis of results, recommendations were developed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Results: The use of CAP is not recommended in children with a previous UTI, with recurrent UTIs, with vesicoureteral reflux (VUR) of any grade, with isolated hydronephrosis, and with neurogenic bladder. CAP is suggested in children with significant obstructive uropathies until surgical correction. Close surveillance based on early diagnosis of UTI episodes and prompt antibiotic therapy is proposed for conditions in which CAP is not recommended. Conclusions: Our systematic review shows that CAP plays a limited role in preventing recurrences of UTI in children and has no effect on its complications. On the other hand, the emergence of new antimicrobial resistances is a proven risk.

Purpose: The purpose of this review is to address the issue of endpoints in paediatric oncology. Oncologists use this term to refer to an outcome they are trying to measure with a clinical trial, which may become accordingly the object of scientific articles. The outcome measured may concern both efficacy and safety, although from different perspectives., Methods: Based on both literature and experience developed in clinical trials, the different types of endpoints have been critically analysed in their power to provide the highest information of therapeutic interest (efficacy and safety) with the least risk and discomfort for the individual. Primary, secondary and surrogate endpoints have been distinguished. The most relevant differences have been discussed in comparison with adult oncology settings of endpoints., Results: The rarity of cancer in childhood and adolescence and the objective difficulty of enrolling statistically conceivable numbers of individuals have determined the utmost positive development of large scale, multinational clinical trials. The most interesting consequence is that the impact of multiplicity interferences, which is usually present in virtually all clinical trials developed for adults with cancer, is not a common event in paediatric oncology. Nevertheless, many of the questions concerning the different impact on outcome and survival of clinical trials developed in adult oncology remain unanswered due to the objective limitations still existing in terms of cure compared with paediatric oncology. The powerful consistency of cure rate, as the most relevant endpoint of clinical trials developed in paediatric oncology, addresses additional considerations to support the relevant differences existing between adult and paediatric oncology: both the development of clinical trials with different aims (confirmatory versus primary response) and the limited impact of multiplicity limitations may determine different implications regarding the meaning of endpoints in paediatric and adult oncology., Conclusion: The aim of cancer treatment is to improve survival (SUR) and quality of life (QoL), but some restraints on the conduct of clinical trials may make these goals unattainable. Clinical trial endpoints represent a measure method aimed to grant answers to questions addressed by the clinical trial itself. The effect of the new regulation is expected to stimulate high-quality research and provide robust information on paediatric drugs to increase the availability of such drugs to children.

Background: The rising awareness of psychological harassment at the workplace means that it is ever more important to collect clinical data and test tools to assess psychiatric disease connected with this phenomenon., Objectives: The aim of the study was to assess the experience gained by the centre for work maladjustment of the University Hospital of Pisa on a sample of patients, using the methods proposed by the centre at the Clinica del Lavoro "Luigi Devoto"., Materials and Methods: The patients were submitted to a diagnostic protocol consisting of work history, medical examination, psychological assessment, psychiatric examination, subjective questionnaires, mood scale and Neutest. The analysis was made in two phases in which 109 subjects were examined to check occupational stress effects in the period March 2002 - July 2004, after which 50 subjects were selected (45.9%) with the adaptation disorder and a history of adverse working conditions., Results: The data gathered showed a slight predominance of workers from the public administration sector. The most representative range of duration of the psychological violence varied from 6 months to 2 years (46%). From close examination of the causes of the maladjustment disorders, structural changes in organization appeared to be the most frequent (13 cases). Among patients with positive diagnosis of disorder caused by psychological violence at the workplace, three situations were prominent: attitude to being a social outcast, behaviour to ignore proposals, and professional declassing., Conclusions: The multidisciplinary approach was culturally very stimulating and fundamental in reaching a final diagnosis of occupational disease: diagnosis of bullying at work and related disease was possible only thanks to the fact that three specialists agreed on the aetiological role of psychological harassment at the workplace. Our experience confirms that psychological harassment can cause health impairment and the most common diagnosis is maladjustment disorder.
